What's your gas mileage.
My -SE gets average 270mi per tank mainly city driving.

Gas smell could be a leaky PD...

idk my average mileage but im pretty sure it's less than that in city driving, i figure bout 200 mile's to the tank (spedo doesnt work ne more so i couldnt tell u exactly)....PD?

You should check your fuel pressure regulator, AFM, injector for leaks.

thafox

where's the fpr? and is there a way to check the injector's for leak's without removing the uim?

don't worry. my SE just smells as bad as yours, but i still get good gas mileage on it. mods are just header and K&N cone style air filter

and RB muffler w/ straight pipe... ............. maybe that's why mine's smell bad!

thafox

yea but your's has mod's...mine's stock aside from an aftermarket muffler that the guy before me put on there

If your injectors are leaky, it would probably flood from time to time... is this the case?

thafox

naw...hasnt flooded on me before

Injectors on SE's tend to crack at the fuel injector top, where the orange plastic piece sits on the metal injector body. This results in fuel spray on top of the lower intake manifold and engine, which is then drafted up past the hood and into your fresh air inlet at the base of the windshield.

Best case is that your injector seals ($7 for each kit x2 at Autozone) need to be replaced, which are the rubber grommets at the top and bottom of the injectors, plus the O-ring that fits up inside the fuel rail. Worst case, you need to replace a cracked injector for about $100 each.

Look for pooled fuel on the lower intake manifold and spraying fuel during idle conditions - you really need to figure this out because fuel vapor and hot exhaust = engine fire. HTH,

Is it easy to visually inspect injectors and/or seals for this type of damage?

LongDuck

Grab a flashlight and look through the intake runners on the upper intake manifold and you can see both injectors there - more importantly, you can see the valley that's formed between the lower intake manifold and the engine block, where the fuel will pool if your injectors are leaking. Grab a flashlight and have a look.

DO NOT USE A LIGHTER FOR THIS TEST!

If you see any damp 'dirt' or grit here, it's likely that your injectors are leaking from somewhere and would necessitate a removal of the upper intake manifold and other intake systems to get to the fuel rail. It could also be something as simple as an old fuel injection line that is past due for a replacement. These systems operate at up to 50psi, so fuel pressure will eventually take it's toll on the rubber feed and return lines under the upper intake manifold. Replace ONLY with fuel INJECTION tubing, not the commonly available fuel line tubing - one is meant for high pressure fuel injection systems, and the other will quickly erode under the pressure and cause a fuel spray that you can't even imagine.

Good luck,
